Chapter VI: Part 6

The sun that shone upon the forgotten planet was actually very near. It shone on the top of the cloud-bank, and the clouds glowed with dazzling whiteness. It shone on the mountain-peaks where they penetrated the mist, and the peaks were warmed, and there was no snow anywhere despite the height. There were winds, here where the sun yielded sensible heat. The sky was very blue. At the edge of the plateau--from which the cloud-banks were down instead of up--the mountainsides seemed to descend into a sea of milk. Great undulations in the mist had the semblance of waves, which moved with great deliberation toward the shores. They seemed sometimes to break in slow-motion against the mountain-walls where they were cliff-like, and sometimes they seemed to flow up gentler inclinations like water flowing up a beach. But all of this was very deliberate indeed, because the cloud-waves were sometimes twenty miles from crest to crest.

The look of things was different on the highlands. This part of the unnamed world, no less than the lowlands, had been seeded with life on two separate occasions. Once the seedings was with bacteria and moulds and lichens to break up the rocks and make soil of them, and once with seeds and insect-eggs and such living things as might sustain themselves immediately they were hatched. But here on the highlands the different climatic conditions had allowed other seedlings and creatures to survive together.

Here moulds and yeasts and rusts were stunted by the sunlight. Grasses and weeds and trees survived, instead. This was an ideal environment for plants that needed sunlight to form chlorophyl, with which to make use of the soil that had been formed. So on the highlands the vegetation was almost earthlike. And there was a remarkable side-effect on the fauna which had been introduced in the same manner and at the same time as the creatures down below. In coolness which amounted to a temperate climate, there developed no such frenzy of life as made the nightmare jungles under the clouds. Plants grow at a slower rate than fungi, and less luxuriantly. There was no vast supply of food for large-sized plant-eaters. Insects which were to survive, here, could not grow to be monsters. Moreover, the nights here were chill. Very many insects grow torpid in the cool of a temperate-zone night, but warm up to activity soon after sunrise. But a large creature, made torpid by cold, will not revive so quickly. If large enough, it will not become fully active until close to dark. On the plateau, the lowland monsters would starve in any case. But more;--they would have only a fraction of each day of full activity.

So there was a necessary limit to the size of the creatures that lived above the clouds. To humans from other planets, the life on the plateau would not have seemed horrifying at all. Save for the absence of birds to sing, and a lack of small mammals to hunt or merely to enjoy, the untouched, sunlit plateau with its warm days and briskly chill nights would have impressed most civilized men as an ideal habitation.

But Burl and his followers were hardly prepared to see it that way at first glance. If told about it in advance, they would have thought of it with despair.

But they did not know beforehand. They toiled upward, their leader moved by such ridiculous motives of pride and vanity as have caused men to achieve greatness throughout all history. Two great continents were discovered back on Earth by a man trying to get spices to hide the gamey flavor of half-spoiled meat, and the power that drives mile-long space-craft was first discovered and tamed by men making bombs to destroy their fellows. There were precedents for foolish motives producing results far from foolishness.

The trudging, climbing folk crawled up the hillside. They reached a place high above the valley Burl had led them to. That valley grew misty in appearance. Presently it could no longer be seen at all. The mist they had taken for granted, all their lives, hid from them everything but the slanting stony wall up which they climbed. The stone was mostly covered by bluish-green rock-tripe in partly overlapping sheets. Such stuff is always close behind the bacteria which first attack a rock-face. On a slope, it clings while soil is washed downward as fast as it is formed. The people never ate rock-tripe, of course. It produces frightening cramps. In time they might learn that when thoroughly dried it can be cooked to pliability again and eaten with some satisfaction. But so far they neither knew dryness nor fire.

Nor had they ever known such surroundings as presently enveloped them. A slanting rocky mountainside, which stretched up frighteningly to the very sky. Grayness overhead. Grayness also to one side,--the side away from the mountain. And equal grayness below. The valley from which they had come could no longer be seen even as a different shading of the mist. And as they scrambled and trudged after Burl, his followers gradually became aware of the utter strangeness of all about them. For one result, they grew sick and dizzy. To them it seemed that all solidity was slowly tilting. Had they been superstitious, they might have thought of demons preparing to punish them for daring to come to such a place. But--quaintly enough--Burl's followers had developed no demonology. Your typical savage is resolved not to think, but he does have leisure to want. He makes gods and devils out of his nightmares, and gambles on his own speculations to the extent of offering blackmail to demons if they will only let him alone or--preferably--give him more of the things he wants.

But the superstitions of savages involve the payment of blackmail in exact proportion to their prosperity. The Eskimos of Earth lived always on the brink of starvation. They could not afford the luxury of tabus and totem animals whose flesh must not be eaten, and forbidden areas which might contain food.

Religion there was, among Burl's people, but superstition was not. No humans, anywhere, can live without religion, but on Earth Eskimos did with a minimum of superstitions,--they could afford no more--and the humans of the forgotten planet could not afford any at all.

Therefore they climbed desperately despite the unparalleled state of things about them. There was no horizon, but they had never seen a horizon. Their feeling was that what had been "down" was now partly "behind" and they feared lest a toppling universe ultimately let them fall toward that grayness they considered the sky.

But all kept on. To lag behind would be to be abandoned in this place where all known sensations were turned topsy-turvy. None of them could imagine turning back. Even old Tama, whimpering in a whisper as she struggled to keep up, merely complained bitterly of her fate. She did not even think of revolt. If Burl had stopped, all his followers would have squatted down miserably to wait for death. They had no thought of adventure or any hope of safety. The only goodnesses they could imagine were food and the nearness of other humans. They had food--nobody had abandoned any of the dangling ant-bodies Tet and Dik had distributed before the climb began. They would not be separated from their fellows.

Burl's motivation was hardly more distinct. He had started uphill in a judicious mixture of fear and injured vanity and desperation. There was nothing to be gained by going back. The terrors at hand were no greater than those behind, so there was no reason not to go ahead.

They came to a place where the mountain-flank sank inward. There was a flat space, and behind it a winding cañon of sorts like a vast crack in the mountain's substance. Burl breasted the curving edge and found flatness beyond it. He stopped short.

The mouth of the cañon was perhaps fifty yards from the lip of the downward slope. So much space was practically level, and on it were toadstools and milkweed--two of them--and there was food. It was a small, isolated asylum for life such as they were used to. They could--it was possible that they could--have found a place of safety here.

But the possibility was not the fact. They saw the spider-web at once. It was slung between the opposite cañon-walls by cables all of two hundred feet long. The radiating cables reached down to anchorages on stone. The snare-threads, winding out and out in that logarithmic spiral whose properties men were so astonished to discover, were fully a yard apart. The web was for giant game. It was empty now, but Burl saw the telegraph-cord which ran from the very center of the web to the web-maker's lurking-place. There was a rocky shelf on the cañon-wall. On it rested the spider, almost invisible against the stone, with one furry leg touching the cable. The slightest touch on any part of the web would warn it instantly.

Burl's followers accumulated behind him. Old Jon's wheezing was audible. Tama ceased her complaints to survey this spot. It might be--it could be--a haven, and she would have to find new and different things to complain about in consequence. The spider-web itself, of course, was no reason for them to be alarmed. Web-spiders do not hunt. Their males do, but they are rarely in the neighborhood of a web save at mating-time. The web itself was no reason not to settle here. But there was a reason.

The ground before the web,--between the web and themselves--was a charnel-house of murdered creatures. Half-inch-thick wing-cases of dead beetles and the cleaned-out carapaces of other giants. The ovipositor of an ichneumon-fly,--see feet of springy, slender, deadly-pointed tube--and the abdomen-plates of bees and the draggled antennae of moths and butterflies.

Something very terrible lived in this small place. The mountainsides were barren of food for big flying things. Anything which did fly this high for any reason would never land on sloping foodless stone. It would land here. And very obviously it would die. Because something--Something--killed things as they came. It denned back in the cañon where they could not see it. It dined here.

The humans looked and shivered, all but Burl. He cast his eyes about for better weapons than he possessed. He chose for himself a magnificent lance grown by some dead thing for its own defense. He pulled it out of the ground.

It was utterly silent, here on the heights. No sounds from the valley rose so high. There was no noise except the small creakings made as Burl strove to free the new, splendid weapon for himself.

That was why he heard the gasp which somebody uttered in default of a scream that would not be uttered. It was a choked, a strangled, an inarticulate sobbing noise.

He saw its cause.

There was a thing moving toward the folk from the recesses of the cañon. It moved very swiftly. It moved upon stilt-like, impossibly attenuated legs of impossible length and inconceivable number. Its body was the thickness of Burl's own. And from it came a smell of such monstrous foetor that any man, smelling it, would gag and flee even without fear to urge him on. The creature was a monstrous millipede, forty feet in length, with features of purest, unadulterated horror.

It did not appear to plan to spring. Its speed of movement did not increase as it neared the tribesfolk. It was not rushing, like the furious charge of the murderers Burl's tribe knew. It simply flowed sinuously toward them with no appearance of haste, but at a rate of speed they could not conceivably outrun.

Sticklike legs twitched upward and caught the spinning body of an ant. The creature stopped, and turned its head about and seized the object its side-legs had grasped. It devoured it. Burl shouted again and again.

There was a rain of missiles upon the creature. But they were not to hurt it, but to divert its incredibly automaton-like attention. Its legs seized the things flung to it. It was not possible to miss. Ten, fifteen,--twenty of the items of small-game were grasped in mid-air, as if they were creatures in flight.

Burl's shoutings took effect. His people fled to the side of the level lip of ground. They climbed frantically past the opening of the valley. They fled toward the heights.

Burl was the last to retreat. The monstrous millipede stood immobile, trapped for the moment by the gratification of all its desires. It was absorbed by the multitude of tiny tidbits with which it had been provided.

It was a fact to Burl's honor that he debated a frantic attack upon the monster in its insane absorption. But the strangling stench was deterrent enough. He fled,--the last of his band of fugitives to leave the place where the monstrous creature lived and preyed. As he left it, it was still crunching the small meals, one by one, with which the folk had supplied it.

They went on up the mountain-flank. It was not to be supposed, of course, that the creature could not move above the slanting rock-surface. Unquestionably it roamed far and wide, upon occasion. But its own foetid reek would make impossible any idea of trailing the humans by scent. And, climbing desperately as the humans did, it would be unable to see them when they were past the first protuberance of the mountain.

In twenty minutes they slackened their pace. Exhaustion prompted it. Caution ordered it. Because here they saw another small island of flatness in the slanting universe which was all they could see save mist. It was simply a place where boulders had piled up, and soil had formed, and there was a miniature haven for life other than moulds which could grow on naked stone.

Actually, there was a space a hundred feet by fifty on which wholly familiar mushrooms grew. It was a thicket like a detached section of the valley itself. Well-known edible fungi grew here. There were gray puffballs. And from it came the cheerful loud chirping of some small beetle, arrived at this spot nobody could possibly know how, but happily ensconsed in a separate bit of mushroom-jungle remote from the dangers of the valley. If it was small enough, it would even be safe from the reeking horror of the cañon just below it.

They broke off edible mushrooms here and ate. And this could have been safety for them--save for the giant millipede no more than half a mile below. Old Jon wheezed querulously that here was food and there was no need for them to go further, just now. Here was food....

Burl regarded him with knitted brows. Jon's reaction was natural enough. The tribesfolk had never tended to think for the future because it was impossible to make use of such planning. Even Burl could easily enough have accepted the fact that this was safety for the moment and food for the moment. But it happened that to settle down here until driven out would--and at this moment--have deprived him of the authority he had so recently learned to enjoy.

"You stay," he said haughtily, to Jon. "I go on, to a better place where nothing is to be feared at all!"

He held out his hand to Saya. He assailed the slope again, heading upward in the mist.

His tribe followed him. Dik and Tet, of course, because they were boys and Burl led on to high adventures in which so far nobody had been killed. Dor followed because--he being the strongest man in the tribe--he had thoughtfully realized that his strength was not as useful as Burl's brains and other qualities. Cori followed because she had children, and they were safer where Burl led than anywhere else. The others followed to avoid being left alone.

The procession toiled on and up. Presently Burl noticed that the air seemed clearer, here. It was not the misty, only half transparent stuff of the valley. He could see for miles to right and left. He realized the curvature of the mountain-face. But he could not see the valley. The mist hid that.

Suddenly he realized that he saw the cloud-bank overhead as an object. He had never thought of it specifically before. To him it had been simply the sky. Now he saw an indefinite lower surface which yet definitely hid the heights toward which he moved. He and his followers were less than a thousand feet below it. It appeared to Burl that presently he would run into an obstacle which would simply keep him from going any further. The idea was disheartening. But until it happened he obstinately climbed on.

He observed that the thing which was the sky did not stay still. It moved, though slowly. A little higher, he could see that there were parts of it which were actually lower than he was. They moved also, but they moved away from him as often as they moved toward him. He had no experience of any dangerous thing which did not leap at its victims. Therefore he was not afraid.

In fact, presently he noticed that the whiteness which was the cloud-layer seemed to retreat before him. He was pleased. Weak things like humans fled from enemies. Here was something which fled at his approach! His followers undoubtedly saw the same thing. Burl had killed spiders. He was a remarkable person. This unknown white stuff was afraid of him. Therefore it was wise to stay close to Burl. Burl found his vanity inflamed by the fact that always--even at its thickest--the white cloud-stuff never came nearer than some dozens of feet. He swaggered as he led his people up.

And presently there was brightness about them. It was a greater brightness than the tribesfolk had ever known. They knew daylight as a grayness in which one could see. Here was a brightness that shone. They were not accustomed to brightness.

They were not accustomed to silence, either. The noises of the valley were like all the noises of the lowlands. They had been in the ears of every one of the human beings since they could hear at all. They had gradually diminished as the valley dropped behind them. Now, in the radiant white mist which was the cloud-layer, there were no sounds at all, and the fact was suddenly startling.

They blinked in the brightness. When they spoke to each other, they spoke in whispers. The stone underfoot was not even lichen-covered, here. It was bare and bright and glistened with wetness. The light they experienced took on a golden tint. All of these things were utterly unparalleled, but the stillness was a hush instead of a menacing silence. The golden light could not possibly be associated with fear. The people of the forgotten planet felt, most likely, the sort of promise in this shining tranquility which before they had known only in dreams. But this was no dream.

They came up through the surface of a sea of mist, and they saw before them a shore of sunshine. They saw blue and sky and sunlight for the first time. The light smote their shins and brilliantly colored furry garments. It glittered in changing, ever-more-colorful flashes upon cloaks made of butterfly wings. It sparkled on the great lance carried by Burl in the lead, and the quite preposterous weapons borne by his followers.

The little party of twenty humans waded ashore through the last of the thinning white stuff which was cloud. They gazed about them with wondering, astonished eyes. The sky was blue. There was green grass. And again there was sound. It was the sound of wind blowing among trees, and of things living in the sunshine.

They heard insects, but they did not know what they heard. The shrill small musical whirrings; the high-pitched small cries which made an elfin melody everywhere,--these were totally strange. All things were new to their eyes, and an enormous exultation filled them. From deep-buried ancestral memories they somehow knew that what they saw was right, was normal, was appropriate and proper, and that this was the kind of world in which humans belonged, rather than the seething horror of the lowlands. They breathed clean air for the first time in many generations.

Burl shouted in his triumph, and his voice echoed among trees and hillsides.

It was time for the plateau to ring with the shouting of a man in triumph!

_10. MEN CLIMB UP TO SAVAGERY_

They had food for days. They had brought mushroom from the isolated thicket not too far beneath the clouds. There were the ants that Dik and Tet had distributed grandly, and not all of which had been used to secure escape from the cañon of the millipede. Had they found other food immediately, they would have settled down comfortably in the fashion normal to creatures whose idea of bliss is a secure hiding-place and food on hand so they do not have to leave it. Somehow they believed that this high place of bright light and new colors was secure. But they had no hiding-place. And though they did accept with the unreasoning faith of children and savages that there were no enemies here, they still wanted one.

They found a cave. It was small, so that it would be crowded with all of them in it, but as it turned out, this was fortunate. At some time it had been occupied by some other creature, but the dirt which floored it had settled flat and showed no tracks. It retained faint traces of a smell which was unfamiliar but not unpleasing,--it held no connotation of danger. Ants stank of formic acid plus the musky odor of their particular city. One could identify not only the kind of ant, but its home city, by sniffing at an ant-trail. Spiders had their own hair-raising odor. The smell of a praying-mantis was acrid, and all beetles reeked of decay. And of course there were those bugs whose main defense was an effluvium which tended to strangle all but the smell's happy possessor. This faint smell in the cave was different. The humans thought vaguely that it might possibly be another kind of man.

Actually, it was the smell of a warm-blooded animal. But Burl and his fellows knew of no warm-blooded creature but themselves.

They had come above the clouds a bare two hours before sunset,--of which they knew nothing. For an hour they marveled, staying close together. They were especially astounded by the sun, since they could not bear to look at it. But presently, being savages, they accepted it matter-of-factly.

They could not cease to wonder at the vegetation about them. They were accustomed only to gigantic fungi and the few straggling plants which tried so desperately to bear seed before they were devoured. Here they saw many plants and no fungi,--and they did not see anything they recognized as insects. They looked only for large things.

They were astounded by the slenderness and toughness of the plants. Grass fascinated them, and weeds. A large part of their courage came from the absence of debris upon the ground. The hunting-grounds of spiders were marked by grisly remnants of finished meals, and where mantises roamed there were bits of transparent beetle-wings and sharp spiny bits of armor not tasty enough to be consumed. Here, in the first hour of their exploration, they saw no sign that an insect like the lowland ones had ever been in this place at all. But they could not believe the monsters never came. They correctly--and pessimistically--assumed that their coming was only rare.

The cave was a great relief. Trees did not grow close enough to give them a feeling of safety,--though they were ludicrously amazed at the invincible hardness of tree trunks. They had never known anything but insect-armour and stone which was as hard as the trunks of those growing things. They found nothing to eat, but they were not yet hungry. They did not worry about food while they still had remnants from their climb.

When the sun sank low and crimson colorings filled the west, they were less happy. They watched the glory of their first sunset with scared, incredulous eyes. Yellows and reds and purples reared toward the zenith. It became possible to look at the sun directly. They saw it descend behind something they could not guess at. Then there was darkness.

The fact stunned them. So night came like this!

Then they saw the stars for the first time, as they came singly into being. And the folk from the lowland crowded frantically into the cave with its faint odor of having once been occupied by something else. They filled the cave tightly. But Burl had some reluctance to admit his terror. He and Saya were the last to enter.

And nothing happened. Nothing. The sounds of sunset continued. They were strange but soothing and somehow--again ancestral memory spoke comfortingly--they were the way night-sounds ought to be. Burl and the others could not possibly know it, but for the first time in forty generations on the forgotten planet, human beings were in an environment really suited to them. It had a rightness and a goodness which was obvious in spite of its novelty. And because of Burl's own special experiences, he was a little bit better able to estimate novelties than the rest. He listened to the night-noises from close by the cave's small entrance. He heard the breathing of his tribesfolk. He felt the heat of their bodies, keeping the crowded enclosure warm enough for all. Saya held fast to his hand, for the reassurance of the contact. He was wakeful, and thinking very busily and painfully, but Saya was not thinking at all. She was simply proud of Burl.

She felt, to be sure, a tumult which was fear of the unknown and relief from much greater fear of the familiar. She felt warm, prideful memories of the sight of Burl leading and commanding the others. She had absorbing fresh memories of the look and feel of sunshine, and mental pictures of sky and grass and trees which she had never seen before. Confusedly she remembered that Burl had killed a spider, no less, and he had shown how to escape a praying-mantis by flinging it at an ant, and he had grandly led the others up a mountainside it had never occurred to anybody else to climb. And the giant millipede would have devoured them all, but that Burl gave commands and set the example, and he had marched magnificently up the mountainside when it seemed that all the cosmos twisted and prepared to drop them into an inverted sky....

Saya dozed. And Burl sat awake, listening, and presently with fast-beating heart he slipped out of the entrance to the cave and stared about him in the night.

There was coolness such as he had never known before, but nightfall was not long past. There were smells in the air he had never before experienced,--green things growing, and the peculiar clean odor of wind that has been bathed in sunshine, and the oddly satisfying smell of resinous trees.

But Burl raised his eyes to the heavens. He saw the stars in all their glory, and he was the first human in two thousand years and more to look at them from this planet. There were myriads upon myriads of them, varying in brightness from stabbing lights to infinitesimal twinklings. They were of every possible color. They hung in the sky above him, immobile and unthreatening. They had not descended. They were very beautiful.

Burl stared. And then he noticed that he was breathing deeply, with a new zest. He was filling his lungs with clean, cool, fragrant air such as men were intended to breathe from the beginning, and of which Burl and many others had been deprived. It was almost intoxicating to feel so splendidly alive and unafraid.

There was a slight sound. Saya stood beside him, trembling a little. To leave the others had required great courage, but she had come to realize that if Burl was in danger she wished to share it.

They heard the nightwind and the orchestra of night-singers. They wandered aside from the cave-mouth and Saya found completely primitive and satisfying pride in the courage of Burl, who was actually not afraid of the dark! Her own uneasiness became something which merely added savor to her pride in him. She followed him wherever he went, to examine this and consider that in the nighttime. It gave her enormous satisfaction at once to think of danger and to feel so safe because of his nearness.

Presently they heard a new sound in the night. It was very far away, and not in the least like any sound they had ever heard before. It changed in pitch as insect-cries do not. It was a baying, yelping sound. It rose, and held the higher note, and abruptly dropped in pitch before it ceased. Minutes later it came again.

Saya shivered, but Burl said thoughtfully:

"That is a good sound."

He didn't know why. Saya shivered again. She said reluctantly:

"I am cold."

It had been a rare sensation in the lowlands. It came only after one of the infrequent thunderstorms, when wetted human bodies were exposed to the gusty winds that otherwise never blew. But here the nights grew cold after sundown. The heat of the ground would radiate to outer space with no clouds to intercept it, and before dawn the temperature might drop nearly to freezing. On a planet so close to its sun, however, there would hardly be more than light hoar-frost at any time.

The two of them went back to the cave. It was warm there, because of the close packing of bodies and many breaths. Burl and Saya found places to rest and dozed off, Saya's hand again trustfully in Burl's.

He still remained awake for a long time. He thought of the stars, but they were too strange to estimate. He thought of the trees and grass. But most of his impressions of this upper world were so remote from previous knowledge that he could only accept them as they were and defer reflecting upon them until later. He did feel an enormous complacency at having led his followers here, though.

But the last thing he actually thought about, before his eyes blinked shut in sleep, was that distant howling noise he had heard in the night. It was totally novel in kind, and yet there was something buried among the items of his racial heritage that told him it was good.

He was first awake of all the tribesmen and he looked out into the cold and pallid grayness of before-dawn. He saw trees. One side was brightly lighted by comparison, and the other side was dark. He heard the tiny singing noises of the inhabitants of this place. Presently he crawled out of the cave again.

The air was biting in its chill. It was an excellent reason why the giant insects could not live here, but it was invigorating to Burl as he breathed it in. Presently he looked curiously for the source of the peculiar one-sided light.

He saw the top of the sun as it peered above the eastern cloud-bank. The sky grew lighter. He blinked and saw it rise more fully into view. He thought to look upward, and the stars that had bewildered him were nearly gone.

He ran to call Saya.

The rest of the tribe waked as he roused her. One by one, they followed to watch their first sunrise. The men gaped at the sun as it filled the east with colorings, and rose and rose above the seemingly steaming layer of clouds, and then appeared to spring free of the horizon and swim on upward.

The women stared with all their eyes. The children blinked, and shivered, and crept to their mothers for warmth. The women enclosed them in their cloaks, and they thawed and peered out once more at the glory of sunshine and the day. Very soon, too, they realized that warmth came from the great shining body in the sky. The children presently discovered a game. It was the first game they had ever played. It consisted of running into a shaded place until they shivered, and then of running out into warm sunshine once more. Until this, dawning fear was the motive for such playing as they did. Now they gleefully made a game of sunshine.

In this first morning of their life above the clouds, the tribesmen ate of the food they had brought from below. But there was not an indefinite amount of food left. Burl ate, and considered darkly, and presently summoned his followers' attention. They were quite contented and for the moment felt no need of his guidance. But he felt need of admiration.

He spoke abruptly:

"We do not want to go back to the place we came from," he said sternly. "We must look for food here, so we can stay for always. Today we find food."

It was a seizure of the initiative. It was the linking of what the folk most craved with obedience to Burl. It was the device by which dictators seize power, and it was the instinctive action of a leader.

The eating men murmured agreement. There was a certain definite idea of goodness--not virtue, but of things desirable--associated with what Burl did and what he commanded. His tribe was gradually forming a habit of obedience, though it was a very fragile habit up to now.

He led them exploring as soon as they had eaten. All of them, of course. They straggled irregularly behind him. They came to a brook and regarded it with amazement. There were no leeches. No greenish algae. No foaming masses of scum. It was dear! Greatly daring, Burl tasted it. He drank the first really potable water in a very long time for his race on this planet. It was not fouled by drainage through moulds or rusts.

Dor drank after him. Jak. Cori tasted, and instantly bade her children drink. Even old Tama drank suspiciously, and then raised her voice in shrill complaint that Burl had not led them to this place sooner. Tet and Dik became convinced that there were no deadly things lurking in it, and splashed each other. Dik slipped and sat down hard on white stuff that yielded and almost splashed. He got up and looked fearfully at what he thought might be a deadly slime. Then he yelped shrilly.

He sat down on and crushed part of a bed of mushrooms. But they were tiny, clean, and appetizing. They were miniatures of the edible mushrooms the tribe fed on.

Burl smelled and finally tasted one. It was, of course, nothing more or less than a perfectly normal edible mushroom, growing to the size that mushrooms originally grew on Earth. It grew on a shaded place in enormously rich soil. It had been protected from direct sunlight by trees, but it had not had the means or the stimulus to become a monster.

Burl ate it. He carefully composed his features. Then he announced the find to his followers. There was food here, he told them sternly, but in this splendid world to which he had led them, food was small. There would be no great enemies here, but the food would have to be sought in small objects instead of great ones. They must look at this place and seek others like it, in order to find food....

The tribesmen were doubtful. But they plucked mushrooms--whole ones!--instead of merely breaking off parts of their tops. With deep astonishment they recognized the miniature objects as familiar things ensmalled. These mushrooms had the same savor, but they were not coarse or stringy or tough like the giants. They melted in the mouth; Life in this place to which Burl had led them was delectable! Truly the doings of Burl were astonishing!

When the oldest of Cori's children found a beetle on a leaf, and they recognized it, and instead of being bigger than a man and a thing to flee from, it was less than an inch in size and helpless against them--. They were entranced. From that moment onward they would really follow Burl anywhere, in the happy conviction that he could only bring good to everybody.

The opinion could have drawbacks, and it need not be always even true, but Burl did nothing to discourage it.

And then, near midday, they made a discovery even greater than that of familiar food in unfamiliar sizes. They were struggling, at the time, through a vast patch of bushes with thorns on them--they were not used to thorns--which they deeply distrusted. Eventually they would find out that the glistening dark fruit were blackberries, and would rejoice in them, but at this first encounter they were uneasy. In the midst of such an untouched berry-patch they heard noises in the distance.

The sound was made up of cries of varying pitch, some of which were loud and abrupt, and others longer and less loud. The people did not understand them in the least. They could have been cries of human beings, perhaps, but they were not cries of pain. Also they were not language. They seemed to express a tremendous, zestful excitement. They had no overtone of horror. And Burl and his folk had known of no excitement among insects except frenzy. They could not imagine what sort of tumult this could be.

But to Burl these sounds had something of the timbre of the yelping noises of the night before. He had felt drawn to that sound. He liked it. He liked this.

He led the way boldly toward the agitated noises. Presently--after a mile or so--he and his people came out of breast-high weeds. Saya was immediately behind him. The others trailed,--Tama complaining bitterly that there was no need to track down sounds which could only mean danger. They emerged in a space of bare stone above a small and grassy amphitheatre. The tumult came from its center.

A pack of dogs was joyously attacking something that Burl could not see clearly. They were dogs. They barked zestfully, and they yelped and snarled and yapped in a dozen different voices, and they were having a thoroughly good time,--though it might not be so good for the thing they attacked.

One of them sighted the humans. He stopped stock-still and barked. The others whirled and saw the humans as they came out into view. The tumult ceased abruptly.

There was silence. The tribesmen saw creatures with four legs only. They had never before seen any living thing with fewer than six,--except men. Spiders had eight. The dogs did not have mandibles. They did not have wing-cases. They did not act like insects. It was stupifying!

And the dogs saw men, whom they had never seen before. Much more important, they smelled men. And the difference between man-smell and insect-smell was so vast--because through hundreds of generations the dogs had not smelled anything with warm blood save their own kind--the difference in smell was so great in kind that the dogs did not react with suspicion, but with a fascinated curiosity. This was an unparalleled smell. It was, even in its novelty, an overwhelmingly satisfying smell.

The dogs regarded the men with their heads on one side, sniffing in the deepest possible amazement,--amazement so intense that they could not possibly feel hostility. One of them whined a little because he did not understand.

_11. WARM BLOOD IS A BOND_

Peculiarly enough, it was a matter of topography. The plateau which reached above the clouds rose with a steep slope from the valley from which a hunting-spider's brood had driven the men. This was on the eastern edge of the plateau. On the west, however, the highland was subject to an indentation which almost severed it. No more than twenty miles from where Burl's group had climbed to sunshine, there was a much more gradual slope downward. There, mushroom-forests grew almost to the cloud-layer. From there, giant insects strayed up and onto the plateau itself.

They could not live above the clouds, of course. There was not food enough for their insatiable hunger. Especially at night, it was too cold to allow them to stay active. But they did stray from their normal environment, and some of them did reach the sunshine, and perhaps some of them blundered back down to their mushroom-forests again. But those which did not stumble back were chilled to torpor during their first night underneath the stars. They were only partly active on the second day,--if, indeed, they were active at all. Few or none recovered from their second nights' coldness. None at all kept their full ferocity and deadliness.

And this was how the dogs survived. They were certainly descended from dogs on the wrecked space-ship--the _Icarus_--whose crew had landed on this planet some forty-odd human generations since. The humans of today had no memories of the ship, and the dogs surely had no traditions. But just because those early dogs had less intelligence, they had more useful instincts. Perhaps the first generations of castaways bred dogs in their first few desperate centuries, hoping that dogs could help them survive. But no human civilization could survive in the lowlands. The humans went back to the primitive state of their race and lived as furtive vermin among monsters. Dogs could not survive there, though humans did linger on, so somehow the dogs took to the heights. Perhaps dogs survived their masters. Perhaps some were abandoned or driven away. But dogs had reached the highlands. And they did survive because giant insects blundered up after them,--and could not survive in a proper environment for dogs and men.

There was even reason for the dogs remaining limited in number, and keenly intelligent. The food-supply was limited. When there were too many dogs, their attacks on stumbling insect giants were more desperate and made earlier, before the monsters' ferocity was lessened. So more dogs died. Then there was an adjustment of the number of dogs to the food-supply. There was also a selection of those too intelligent to attack rashly. Yet those who had insufficient courage would not eat.

In short, the dogs who now regarded men with bright, interested eyes were very sound dogs. They had the intelligence needed for survival. They did not attack anything imprudently, but they also knew that it was not necessary to be more than reasonably wary of insects in general,--not even spiders unless they were very newly arrived from the steaming lowlands. So the dogs regarded men with very much the same astonished interest with which the men regarded the dogs.

Burl saw immediately that the dogs did not act with the blind ferocity of insects, but with an interested, estimative intelligence strikingly like that of men. Insects never examined anything. They fled or they fought. Those who were not carnivorous had no interest in anything but food, and those who were meat-eaters lumbered insanely into battle at the bare sight of possible prey. The dogs did neither. They sniffed and they considered.

Burl said sharply to his followers:

"Stay here!"

He walked slowly down into the amphitheatre. Saya followed him instantly. Dogs moved warily aside. But they raised their noses and sniffed. They were long, luxurious sniffs. The smell of human kind was a good smell. Dogs had lived hundreds of their generations without having it in their nostrils, but before that there were thousands of generations to whom that smell was a necessity.

Burl reached the object the dogs had been attacking. It lay on the grass, throbbing painfully. It was the larva of an azure-blue moth which spread ten-foot wings at nightfall. The time for its metamorphosis was near, and it had traveled blindly in search of a place where it could spin its cocoon safely and change to its winged form. It had come to another world,--the world above the clouds. It could find no proper place. Its stores of fat had protected it somewhat from the chill. But the dogs had found it as it crawled blindly--.

Burl considered. It was the custom of wasps to sting creatures like this at a certain special spot,--apparently marked for them by a tuft of dark fur.

Burl thrust home with his lance. The point pierced that particular spot. The creature died quickly and without agony. The thought to kill was an inspiration. Then instinct followed. Burl cut off meat for his tribesmen. The dogs offered no objection. They were well-fed enough. Burl and Saya, together, carried the meat back to the other tribesfolk. On the way Burl passed within two yards of a dog which regarded him with extreme intentness and almost a wistful expression. Burl's smell did not mean game. It meant--something the dog struggled helplessly to remember. But it was good.

"I have killed the thing," said Burl to the dog, in the tone of one addressing an equal. "You can go and eat it now. I took only part of it."

Burl and his people ate of what he had brought back. Many of the dogs--most of them--went to the feast Burl had left. Presently they were back. They had no reason to be hostile. They were fed. The humans offered them no injury, and the humans smelled of something that appealed to the deepest well-springs of canine nature.

Presently the dogs were close about the humans. They were fascinated. And the humans were fascinated in return. Each of the people had a little of the feeling that Burl had experienced as the tribal leader. In the intent, absorbed and wholly unhostile regard of the dogs, even children felt flattered and friendly. And surely in a place where everything else was so novel and so satisfactory, it was possible to imagine friendliness with creatures which were not human, since assuredly they were not insects.

A similar state of mind existed among the dogs.

Saya had more meat than she desired. She glanced among the members of the tribe. All were supplied. She tossed it to a dog. He jerked away alertly, and then sniffed at it where it had dropped. A dog can always eat. He ate it.

"I wish you would talk to us," said Saya hopefully.

The dog wagged his tail.

"You do not look like us," said Saya interestedly, "but you act like we do. Not like the--Monsters."

The dog looked significantly at meat in Burl's hand. Burl tossed it. The dog caught it with a quick snap, swallowed it, wagged his tail briefly and came closer. It was a completely incredible action, but dogs and men were blood-kin on this planet. Besides, there was racial-memory rightness in friendship between men and dogs. It was not hindered by any past experience of either. They were the only warm-blooded creatures on this world. It was a kinship felt by both.

Presently Burl stood up and spoke politely to the dog. He addressed him with the same respect he would have given to another man. In all his life he had never felt equal to an insect, but he felt no arrogance toward this dog. He felt superior only to other men.

"We are going back to our cave," he said politely. "Maybe we will meet again."

He led his tribe back to the cave in which they had spent the previous night. The dogs followed, ranging on either side. They were well-fed, with no memory of hostility to any creature which smelled of warm blood. They had an instinct without experience to dull it. The latter part of the journey back to the tribal cave was--if anybody had been qualified to notice it--remarkably like a group of dogs taking a walk with a group of people. It was companionable. It felt right.

That night Burl left the cave, as before, to look at the stars. This time Saya went with him matter-of-factly. But as they came out of the cave-entrance there was a stirring. A dog rose and stretched himself elaborately, yawning the while. When Burl and Saya moved away, he trotted amiably with them.

They talked to it, and the dog seemed pleased. It wagged its tail.

When morning came, the dogs were still waiting hopefully for the humans to come out. They appeared to expect the people to take another nice long walk, on which they would accompany them. It was a brand-new satisfaction they did not want to miss. After all, from a dog's standpoint, humans are made to take long walks with, among other things. The dogs greeted the people with tail-waggings and cordiality.

The dogs made a great difference in the adjustment of the tribe to life upon the plateau. Their friendship assured the new status of human life. Burl and his fellows had ceased to be fugitive game for any insect murderer. They had hoped to become unpursued foragers,--because they could hardly imagine anything else. But when the dogs joined them, they were immediately raised to the estate of hunters. The men did not domesticate the dogs. They made friends with them. The dogs did not subjugate themselves to the men. They joined them,--at first tentatively, and then with worshipful enthusiasm. And the partnership was so inevitably a right one that within a month it was as if it had always been.

Actually, save for a mere two thousand years, it had been.

At the end of a month the tribe had a permanent encampment. There were caves at a suitable distance from the slope up which most wanderers from the lowlands came. Cori's oldest child found the chrysalis of a giant butterfly, whose caterpillar form had so offensive an odor that the dogs had not attacked it. But when it emerged from the chrysalis, men and dogs together assailed it before it could take flight. They ended the enterprise with warm mutual approval. The humans had acquired great wings with which to make warm cloaks,--very useful against the evening chill. Dogs and men, alike, had feasted.

Then, one dawning, the dogs made a vast outcry which awoke the tribesmen. Burl led the rush to the spot. They did battle with a monster nocturnal beetle, less chilled than most such invaders. In the gray dawnlight Burl realized that the darting, yapping dogs kept the creature's full attention. He crippled, and then killed it with his spear. The feat appeared to earn him warm admiration from the dogs. Burl wore a moth's feathery antenna again, bound to his forehead like a knight's plumes. He looked very splendid.

The entire pattern of human life changed swiftly, as if an entire revelation had been granted to men. The ground was often thorny. One man pierced his foot. Old Tama, scolding him for his carelessness, bound a strip of wing-fabric about it so he could walk. The injured foot was more comfortable than the one still unhurt. Within a week the women were busily contriving diverse forms of footgear to achieve greater comfort for everybody. One day Saya admired glistening red berries and tried to pluck one, and they stained her fingers. She licked her fingers to clean them,--and berries were added to the tribe's menu. A veritable orgy of experiment began, which is a state of things which is extremely rare in human affairs. A race with an established culture and tradition does not abandon old ways of doing things without profound reason. But men who have abandoned their old ways can discover astonishingly useful new ones.

Already the dogs were established as sentries and watchmen, and as friends to every member of the tribe. By now mothers did not feel alarmed if a child wandered out of sight. There would be dogs along. No danger could approach a child without vociferous warning from the dogs. Men went hunting, now, with zestful tail-wagging dogs as companions in the chase. Dor killed a torpid minotaur-beetle alone, save for assisting dogs, and Burl felt a twinge of jealousy. But then Burl, himself, battled a black male spider in a lone duel,--with dogs to help. By the time a stray monster from the lowlands reached this area, it was dazed and half-numbed by one night of continuous chill. Even the black spider could not find the energy to leap. It fought like a fiend, yet sluggishly. Burl killed this one while the dogs kept it busy,--and the dogs were reproachful because he carried it back to the tribal headquarters before dividing it among his assistants. Afterward, he realized that though he could have avoided the fight he would have been ashamed to do so, while the dogs barked and snapped at its furry legs.

It was while things were in this state that the way of life for human beings on the forgotten planet was settled for all time. Burl and Saya went out early one morning with the dogs, to hunt for meat for the village. Hunting was easiest in the early hours, while creatures that strayed up the night before were still sluggish with cold. Often, hunting was merely butchery of an enfeebled monster to whom any effort at all was terribly difficult.
